When we cannot figure out how wide the terminal is, we use a
fallback value of 80 ourselves (which cannot be avoided), but when
we run the pager, we export it in COLUMNS, which forces the pager
to use the hardcoded value, even when the pager is perfectly
capable to figure it out itself. Stop exporting COLUMNS when we
fall back on the hardcoded default value for our own use.

We have a custom match_pattern_list() function which we use for matching
test names (like "t1234") against glob-like patterns (like "t1???") for
$GIT_SKIP_TESTS, --verbose-only, etc.
Those patterns may have multiple whitespace-separated elements (e.g.,
"t0* t1234 t5?78"). The callers of match_pattern_list thus pass the
strings unquoted, so that the shell does the usual field-splitting into
separate arguments.
But this also means the shell will do the usual globbing for each
argument, which can result in us seeing an expansion based on what's in
the filesystem, rather than the real pattern. For example, if I have the
path "t5000" in the filesystem, and you feed the pattern "t?000", that
_should_ match the string "t0000", but it won't after the shell has
expanded it to "t5000".
This has been a bug ever since that function was introduced. But it
didn't usually trigger since we typically use the function inside the
trash directory, which has a very limited set of files that are unlikely
to match. It became a lot easier to trigger after edc23840b0 (test-lib:
bring $remove_trash out of retirement, 2021-05-10), because now we match
$GIT_SKIP_TESTS before even entering the trash directory. So the t5000
example above can be seen with:
GIT_SKIP_TESTS=t?000 ./t0000-basic.sh
which should skip all tests but doesn't.
We can fix this by using "set -f" to ask the shell not to glob (which is
in POSIX, so should hopefully be portable enough). We only want to do
this in a subshell (to avoid polluting the rest of the script), which
means we need to get the whole string intact into the match_pattern_list
function by quoting it. Arguably this is a good idea anyway, since it
makes it much more obvious that we intend to split, and it's not simply
sloppy scripting.

Some tests will fail under --verbose because while we've unset COLUMNS
since b1d645b58ac (tests: unset COLUMNS inherited from environment,
2012-03-27), we also look for the columns with an ioctl(..,
TIOCGWINSZ, ...) on some platforms. By setting COLUMNS again we
preempt the TIOCGWINSZ lookup in pager.c's term_columns(), it'll take
COLUMNS over TIOCGWINSZ,
This fixes t0500-progress-display.sh., which broke because of a
combination of the this issue and the progress output reacting to the
column width since 545dc345ebd (progress: break too long progress bar
lines, 2019-04-12). The t5324-split-commit-graph.sh fails in a similar
manner due to progress output, see [1] for details.
The issue is not specific to progress.c, the diff code also checks
COLUMNS and some of its tests can be made to fail in a similar
manner[2], anything that invokes a pager is potentially affected.
See ea77e675e56 (Make "git help" react to window size correctly,
2005-12-18) and ad6c3739a33 (pager: find out the terminal width before
spawning the pager, 2012-02-12) for how the TIOCGWINSZ code ended up
in pager.c

We query `TIOCGWINSZ` in Git to determine the correct value for
`COLUMNS`, and then set that environment variable.
If `TIOCGWINSZ` is not available, we fall back to the hard-coded value
80 _and still_ set the environment variable.
On Windows this is a problem. The reason is that Git for
Windows uses a version of `less` that relies on the MSYS2 runtime to
interact with the pseudo terminal (typically inside a MinTTY window,
which is also aware of the MSYS2 runtime). Both MinTTY and `less.exe`
interact with that pseudo terminal via `ioctl()` calls (which the MSYS2
runtime emulates even if there is no such thing on Windows).
Since https://github.com/gwsw/less/commit/bb0ee4e76c2, `less` prefers
the `COLUMNS` variable over asking ncurses itself.
But `git.exe` itself is _not_ aware of the MSYS2 runtime, or for that
matter of that pseudo terminal, and has no way to call `ioctl()` or
`TIOCGWINSZ`.
Therefore, `git.exe` will fall back to hard-coding 80 columns, no matter
what the actual terminal size is.
But `less.exe` is totally able to interact with the MSYS2 runtime and
would not actually require Git's help (which actually makes things
worse here). So let's not override `COLUMNS` on Windows.
Let's just not set `COLUMNS` unless we managed to query the actual value
from the terminal.
This fixes https://github.com/git-for-windows/git/issues/3235

Currently "git pull --rebase" takes a shortcut in the case a
fast-forward merge is possible; run_merge() is called with --ff-only.
However, "git merge" didn't have an --autostash option, so, when "git
pull --rebase --autostash" was called *and* the fast-forward merge
shortcut was taken, then the pull failed.
This was fixed in commit f15e7cf5cc (pull: ff --rebase --autostash
works in dirty repo, 2017-06-01) by simply skipping the fast-forward
merge shortcut.
Later on "git merge" learned the --autostash option [a03b55530a
(merge: teach --autostash option, 2020-04-07)], and so did "git pull"
[d9f15d37f1 (pull: pass --autostash to merge, 2020-04-07)].
Therefore it's not necessary to skip the fast-forward merge shortcut
anymore when called with --rebase --autostash.
Let's always take the fast-forward merge shortcut by essentially
reverting f15e7cf5cc.
